Question

If 2 is a zero of the polynomial P of x is equal to 2 x square - 3 x + 7a find the value of a

Answer 1

$hey \: mate \: here \: is \: your \: answer...$

$2 {x}^{2} - 3x + 7a = 0$
$\: \: \: on \: putting \: x = 2$
$2(2) {}^{2} - 3(2) + 7a = 0$
$2(4) - 3(2) + 7a = 0$
$8 - 6 + 7a = 0$
$2 + 7a = 0$
$7a = - 2$
$a = \frac{ - 2}{7}$

$the \: value \: of \: a \: is \: \frac{ - 2}{7}$
